In September 1989, the media alleged that the president CDU leader, Uwe Barschel, had launched a plot to have his SDP rival, Bjorn Engholm, charged with tax evasion. It was even said that Barschel had arranged bugs in Engholm's office and had a private detective spy on him. Despite constant denials, Barschel was forced to resign in October. He was found dead 10 days later. Officially, he had committed suicide but those close to him alleged foul play. The media began an extensive campaign and Engholm was forced to resign in 1993.
